The _info.txt file speaks of a generic version 0.2.97.44, but now the version 0.2.97.44 is still in WIP, therefore the roms vary (and not a little) according to the version of the core. In batocera 5.26 what is the version of FBneo used?
Nobody knows which core is used? It is important to know it because it depends on the .dat to create the correct romset.
Just take the last dat / romset, only a few roms a not working, the ones added at the very end of last May
So FBNeo core is around May 15th 2020 commit, something like that
